Filed: 1972-11-06
Abstract: 1394696 Writing and updating digital data on magnetic tape INTERNATIONAL BUSINESS MACHINES CORP 6 Nov 1972 [16 Dec 1971] 51118/72 Headings G5R and G4C To enable a selected one of a series of data blocks D written on magnetic tape 10 to be re-written, using tape transports with different tape speeds (known not to exceed a certain maximum speed), so that the physical length of the block is changed on re-writing, each block D when first written is allocated a length of tape D + P equal to that required by the block for maximum speed writing. Tape length is measured by counting pulses from a tachometer attached to a drive capstan (11), Fig. 2 (not shown). The length to be allocated is computed from the number (N) of bytes in the block to be recorded, and from the number (K) of bytes recorded per tachometer pulse at maximum tape speed. A counter 41 is set to the tachometer count (N/K) corresponding to this length, and tachometer pulses are then subtracted therefrom as the block is recorded via circuits 39 and OR-gate 45. At the end of the block D, padding signals P are generated at 51 and recorded to fill the allocated length. These signals may be all zeroes, ones, or erased tape. The padding generator 51 is turned off when the counter reaches zero or a reference count. If counter 41 exceeds a threshold 54, data processing is interrupted.

Abstract: 1,235,097. Hydrostatic transmission control. SPERRY RAND CORP. 27 Oct., 1969 [14 Nov., 1968], No. 52463/69. Heading F2D. A control for sharing the load between two hydrostatic transmissions A, B driving a common output shaft 18 comprises a servo 54 which adjusts the displacement of the pump 34 of the transmission B in response to the pressure differential in the high pressure lines 22, 36 of the transmissions. As shown a first hydrostatic transmission A has an electric motor 30 driving a variable displacement pump 20 in closed circuit with a fixed displacement motor 26 geared to the output shaft 18. The second transmission B has an electric motor 46 driving a variable displacement pump 34 in closed circuit with a fixed displacement motor 40 which is geared to the output shaft 18. The displacement of the pump 20 is controlled by a hand lever 28. The displacement of the pump 34 is controlled by a servo piston 54 axially slidable in a cylinder 50 supplied with pressure liquid from the high pressure lines 22, 36 through ducts 62, 64. If one transmission transmits more than its share of the load the pressure in its high pressure line (e.g. 22) rises. This increase in pressure is transmitted to the chamber 58 of the servo motor to move the piston 42 which increases the displacement of the pump 34, the pressure in the line 36 and thus the load transmitted by the second hydrostatic transmission. The servo 54 thus adjusts the displacement of the pump 34 to maintain the loads transmitted through the two transmissions equal.

Title: Detent mechanism eg for a timer
IPC: H01H43/04
Filed: 1972-11-17
Abstract: 1393109 Latches SEIKO KOKI KK 17 Nov 1972 [18 Nov 1971] 53219/72 Heading E2A [Also in Division H1] A detent mechanism, suitable for use with switch contacts of a timer, comprises a movable part 1 or 21, means 6 or 25 for urging the movable part away from a predetermined position, the movable part being manually movable in the opposite direction; means actuated by the movement of the movable part in said opposite direction for effecting relative movement between an abutment member 5 or 21a and a substantially planar detent member 3 or 22 so that the latter is releasably held in engagement with the abutment member, this engagment holding the movable part in the said predetermined position, further movement of the movable part in the said opposite direction releasing the said engagement; and a movable member 11 or 23 for causing at least a part of the detent member to be tilted in a direction perpendicular to its plane so as to release the said engagement. Two embodiments are described for use with the timing mechanism of Specification 1393108 (see Division H1). In the first a detent member 3 is flexibly pivoted at 2b on a triangular plate 2 having a fixed pivot 2c and coupled to slidable member 1 by means of pin 2a and slot 1b. Springs 6 and 7 act as shown on member 1 and detent 3. When manual pressure on portion 1d moves member 1 to actuate contact blade 8b the detent 3 is pivoted back such that a fixed pin 5 abuts portion 3b (Fig 2, not shown) and on release of the manual pressure portion 3c engages pin 5 to latch member 1 with contact blades 8b, 8c closed (Fig 3, not shown). Member 1, and hence the switch contacts, may be restored by momentary further pressure on 1d which lifts a tongue 3d above pin 5 such that the detent 3 is freed from the pin and the condition shown in Figure 1 is restored. Alternatively, since in the latched condition detent 3 is raised to lie partly over the end of a shaft 11, axial movement of shaft 11 by the timing mechanism (not shown) will tilt the detent 3 out of the plane of the drawing to clear pin 5 and allow member 1 to restore. In the second embodiment (Fig 5) the detent 22 has a fixed pivot 24a and the abutment pin 21a is carried on slidable member 21. The switch contacts of Fig 1 are replaced by a microswitch M.S. and a timer shaft 23 acts on the detent 22 via a pushrod or lever 27.

In a rotary positive-displacement fluid-pump, or motor, an externally-toothed inner-member, or star member, 26, Figs. 1 and 2, meshes with a stationary internally-toothed outer-member, or ring member, 14, the star member being coupled to a rotatable driving, or power-output, shaft 36 by a plurality of rollers 42 lodged therebetween in part-cylindrical recesses 40 so that the star member is capable of planetary motion relative to the ring member to effect either a pumping action or a motoring action. The star member has at least one tooth less than the ring member, working spaces defined by the teeth being sequentially and periodically connected to inlet and outlet ports 18, 19 in a casing section 10 by a rotary valve-member 52 that co-operates with a plurality of passages 56 in another casing section 12 and is driven by the shaft 36 through pins 54. Each of the passages 56 communicates with a corresponding space between the teeth on the ring member. Alternatively, the star member is constituted by an externally-toothed portion 138, Fig. 5, of the driving, or power-output, shaft and meshes with an internally-toothed ring member 121 that is coupled to a fixed casing-section 114 by a plurality of rollers 128 situated therebetween in part-cylindrical recesses 126 so that when the said shaft rotates about its longitudinal axis the ring member is capable of orbital motion relative to the said casing section without revolving about its own axis. With this arrangement, the pump or motor is otherwise identical to that shown in Figs. 1 and 2.

Abstract: 1321166 Inductors and transformers ALLMANNA SVENSKA ELEKTRISKA AB 22 Nov 1971 [23 Nov 1970] 54097/71 Heading HIT Insulation for layer windings is formed from a tape 3 which has a width greater than the dimension of the conductor 4 in a direction parallel to the coil axis and is wound on the coil former with a pitch greater than that of the conductor winding and at the same time as the conductor. For the greater part of the winding, the insulating tape is wound in advance of the conductor. The conductor itself is insulated either with paper or varnish. During winding of the coil the winding pitch of the insulating tape is adjusted to be effectively zero at the ends of the coil former thus causing the insulation to be wound over itself forming a shoulder 6 which acts as an edge support for the conductor layers. The insulating tape is coated with transverse strips of adhesive 5, which when cured, attach the insulating turns and layers to each other and to the conductor.  The winding pitch of the tape in between the edge supports is arranged to give a maximum thickness of insulation at parts of the coil where there is a maximum potential difference between adjacent conductor layers. In a further embodiment of the invention the edge supports are formed from a separate thinner tape. If the conductor is in the form of a flat tape the edge supports can be omitted altogether.

Abstract: 1333104 Valves MOTO METER GmbH 19 Nov 1970 [12 Oct 1970] 55045/70 Addition to 1333105 Heading F2V Successive pressures, e.g. in the combustion chambers of rotary or orbital piston engines, are monitored, by an arrangement which includes a valve device 101 responsive to the successive pressures applied to an inlet 118. The valve comprises a piston 105 which reciprocates in a cylinder 102 in phase with the pressures, and is caused to rotate so as to connect the inlet 118 selectively with a number of outlets connected, e.g., to pressure gauges 120. The rotation is caused by serrated edges 144 and 148 in the piston co-operating with edges 146 and 150 in the cylinder. Movement of the piston upwardly uncovers a channel 111 so that inlet pressure applied to chamber 103 drives the piston downwardly. Towards the end of this movement another channel 112 permits the pressure in chamber 103 to leak away.
